RE Tire size; I just painted the OE wheels Piano Black and installed General Grabber A/Ts 285/60/20 For me they are the perfect balance of an aggressive tire and great tire on the road. As a side note

285/65/r20 Nitto Ridge Grapplers - No lift - No spacers - Stock wheels

 

That's 34.8" Diameter

 

It fits - no rubbing

Looks great!  I am going to leave my at4 as is without a level or lift.  Can anyone compare the Nitto Ridge Grapplers to K02's?  I had K02's on my '18 and liked them.  Never had the NRG's.

I had K02s on my last truck and I hear slightly less Road noise from the NRGs. 
That being said - there is no guarantee the noise insulation on the trucks themselves isn’t different.

Why would some AT4s come with 20s while others come with 18s? Which package dictated the difference? I have the AT4 with 18s and alot of posts are of 20s...[emoji1745]

I've read and read and I am still unsure.

 

I know I want to go with BFG KM3's on my bone stock 2020 AT4. IN 285 width they only come in 55 ratio which I don't want because I don't want to go smaller. I can't decide if I should just stay with the 275/65/20 or try the 295/60/20. Even the stock 275/60/20 Goodyears are only about 5/8' from the control arm.

I read a lot on here before buying wheels and tires but never found exactly what I needed, so I thought I'd post my results for someone in the future.

 

I didn't want 20x10s because they stick out so far and because the tires always seem to rub. I did wanted to get out from under the wheel well a LITTLE, but was limited in wheels that I liked and available offset. Decided to go 20x9 +1mm offset.

 

For tires I wanted wider, and a little taller, but wasn't obsessed with max height. I don't like when tires are stuffed inside, and I HATE when tires rub. Why spend $50k and then have tires grinding into plastic or worse yet, cut your truck up to clear tires?   Ended up going 295/55-20 BFG ATs. I could have possibly run 295/60s, but was not willing to risk rubbing and no returns once mounted. I've seen others run 295/60, but not on a +1 offset.  Now that I have these in there, going 295/60 with this offset would have likely rubbed.  285/60 was also an option, but quite a bit more expensive and like I said, I cared more about width than height.

 

End results are great. No rub and has about 1/2" clearance at full lock leaving room for articulation off road with no run. The +1 offset left plenty of room for the upper control arm. Tires are about 1/2" outside fenders.

 

Mileage took a hit with these heavy ass tires, but I'm pretty happy with the look.  For reference, this is a stock 2019 AT4 with a rough country front level kit.

From what I'm reading on here and a FB group, it seems that no one is having a problem with the Motofab 1.5 lift. Has anyone experienced an issue? Like ball joint,etc.

I have had the 1.5” level for a year now and about 12k miles. I would still like to upgrade the UCA just because of the failure’s I have seen on FB but you are correct all the one’s I have seen failed are 2” level spacers which is what may be helping my controls stay okay so far. Hope it stays that way until I upgrade

I've had mine on for a while now, almost a year and a ton of miles... with no issues. For sure the ones I've seen are 2inch RC ones. Only 2 or 3, but there was also a guy with a completely stock truck with an issue. About to need tires and was about to go a little beefier ones.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
